6bd8f0502d Call to ‘asList’ with only one argument could be replaced with ‘singletonList’ (#9288)
Motivation:

asList should only be used if there are multiple elements.

Modification:

Call to asList with only one argument could be replaced with singletonList

Result:

Cleaner code and a bit of memory savings

039087ed47 Don't filter out TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (#9274)
Motivation:

TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 is supported since Java 8 (see https://docs.oracle.com/javase/8/docs/technotes/guides/security/SunProviders.html) and belongs to the recommended configurations in many references, eg SSLabs (https://github.com/ssllabs/research/wiki/SSL-and-TLS-Deployment-Best-Practices) or Google Cloud Platform Restricted Profile.

Modifications:

Add TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 to default ciphers list.

Result:

TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 is enabled by default.

Recycle RecyclableArrayDeque as fast as possible in FlowControlHandler (#9263)
Motivation:

FlowControlHandler does use a recyclable ArrayDeque internally but only recycles it when the channel is closed. We should better recycle it once it is empty.

Modifications:

Recycle the deque as fast as possible

Result:

Less RecyclableArrayDeque instances.

b1fb40e42d Change Scheduled to FixedRate in Traffic Counter (#9245)
Motivation:

Traffic shaping needs more accurate execution than scheduled one. So the
use of FixedRate instead.
Moreover the current implementation tends to create as many threads as
channels use a ChannelTrafficShapingHandlern, which is unnecessary.

Modifications:

Change the executor.schedule to executor.scheduleAtFixedRate in the
start and remove the reschedule call from run monitor thread since it
will be restarted by the Fixed rate executor.
Also fix a minor bug where restart was only doing start() without stop()
before.

Result:

Threads are more stable in number of cached and precision of traffic
shaping is enhanced.

96feca1d23 SslHandler to fail handshake and pending writes if non-application write fails (#9240)
Motivation:
SslHandler must generate control data as part of the TLS protocol, for example
to do handshakes. SslHandler doesn't capture the status of the future
corresponding to the writes when writing this control (aka non-application
data). If there is another handler before the SslHandler that wants to fail
these writes the SslHandler will not detect the failure and we must wait until
the handshake timeout to detect a failure.

Modifications:
- SslHandler should detect if non application writes fail, tear down the
channel, and clean up any pending state.

Result:
SslHandler detects non application write failures and cleans up immediately.

8ce3d52c0e OpenSsl.USE_KEYMANAGER_FACTORY incorrectly set to false with BoringSSL (#9175)
Motivation

SSL unit tests started failing for me (RHEL 7.6) after #9162. It looks
like the intention was to prevent disable use of the
io.netty.handler.ssl.openssl.useKeyManagerFactory property when using
BoringSSL, but it now gets set to false in that case rather than the
prior/non-BoringSSL default of true.

Modification

Set useKeyManagerFactory to true rather than false in BoringSSL case
during static init of OpenSSl class.

Result

Tests pass again.

Correctly detect that KeyManagerFactory is not supported when using OpenSSL 1.1.0+ (#9170)
Motivation:

How we tried to detect if KeyManagerFactory is supported was not good enough for OpenSSL 1.1.0+ as it partly provided the API but not all of what is required.

This then lead to failures like:

[ERROR] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 1.102 s <<< FAILURE! - in io.netty.channel.epoll.EpollDomainSocketStartTlsTest

Result:

Also correctly work when OpenSSL 1.1.0 is used.

Log deprecation info message when using 'io.netty.handler.ssl.openssl.useKeyManagerFactory' and ignore it when using BoringSSL (#9162)
Motivation:

When we added support for KeyManagerFactory we also allowed to disable it to make the change less risky. This was done years ago and so there is really no need to use the property anyway.
Unfortunally due a change in netty-tcnative it is even not supported anymore when using BoringSSL.

Modifications:

- Log an info message to tell users that 'io.netty.handler.ssl.openssl.useKeyManagerFactory' is deprecated when it is used
- Ignore 'io.netty.handler.ssl.openssl.useKeyManagerFactory' when BoringSSL is used.

Result:

Fixes https://github.com/netty/netty/issues/9147.

Only use static Exception instances when we can ensure addSuppressed … (#9152)
Motivation:

OOME is occurred by increasing suppressedExceptions because other libraries call Throwable#addSuppressed. As we have no control over what other libraries do we need to ensure this can not lead to OOME.

Modifications:

Only use static instances of the Exceptions if we can either dissable addSuppressed or we run on java6.

Result:

Not possible to OOME because of addSuppressed. Fixes https://github.com/netty/netty/issues/9151.

Add missing assume checks to skip tests if KeyManagerFactory can not be used (#9148)
Motivation:

Depending on what OpenSSL library version we use / system property that is set we need to skip tests that use KeyManagerFactory.

Modifications:

Add missing assume checks for tests that use KeyManagerFactory.

Result:

All tests pass even if KeyManagerFactory is not supported

3221bf6854 Remove the Handler only after it has initialized the channel (#9132)
Motivation:

Previously, any 'relative' pipeline operations, such as
ctx.pipeline().replace(), .addBefore(), addAfter(), etc
would fail as the handler was not present in the pipeline.

Modification:

Used the pattern from ChannelInitializer when invoking configurePipeline().

Result:

5a27f2f78b Allow to specify KeyStore type in SslContext (#9003)
Motivation:

As brought up in https://github.com/netty/netty/issues/8998, JKS can be substantially faster than pkcs12, JDK's new default. Without an option to set the KeyStore type you must change the configuration of the entire JVM which is impractical.

Modification:

- Allow to specify KeyStore type
- Add test case

Result:

Fixes https://github.com/netty/netty/issues/8998.

Introduce DynamicAddressConnectHandler which can be used to dynamically change remoteAddress / localAddress when a connect is issued (#8982)
Motivation:

Bootstrap allows you to set a localAddress for outbound TCP connections, either via the Bootstrap.localAddress(localAddress) or Bootstrap.connect(remoteAddress, localAddress) methods. This works well if you want to bind to just one IP address on an interface. Sometimes you want to bind to a specific address based on the resolved remote address which should be possible.

Modifications:

Add DynamicAddressConnectHandler and tests

Result:

Fixes https://github.com/netty/netty/issues/8940.

c8ff76ba91 [openssl] fix refcount bug in OpenSslPrivateKeyMaterial ctor
Motivation:

Subclasses of `OpenSslKeyMaterial` implement `ReferenceCounted`. This means that a new object should have an initial refcount of 1. An `OpenSslPrivateKey.OpenSslPrivateKeyMaterial` object shares its refcount with the enclosing `OpenSslPrivateKey` object. This means the enclosing object's refcount must be incremented by 1 when an instance of `OpenSslPrivateKey.OpenSslPrivateKeyMaterial` is created. Otherwise, when the key material object is `release()`-ed, the refcount on the enclosing object will drop to 0 while it is still in use.

Modification:

- Increment the refcount in the constructor of `OpenSslPrivateKey.OpenSslPrivateKeyMaterial`
- Ensure we also always release the native certificates as well.

Result:

Refcount is now correct.

Throw SignatureException if OpenSslPrivateKeyMethod.* return null to prevent segfault (#9100)
Motivation:

While OpenSslPrivateKeyMethod.* should never return null we should still guard against it to prevent any possible segfault.

Modifications:

- Throw SignatureException if null is returned
- Add unit test

Result:

No segfault when user returns null.

Only try to use OpenSslX509TrustManagerWrapper when using Java 7+ (#9065)
Motivation:

We should only try to use OpenSslX509TrustManagerWrapper when using Java 7+ as otherwise it fail to init in it's static block as X509ExtendedTrustManager was only introduced in Java7

Modifications:

Only call OpenSslX509TrustManagerWrapper if we use Java7+

Make validation tools more happy by not have TrustManager impl just accept (#9041)
Motivation:

Seems like some analyzer / validation tools scan code to detect if it may produce some security risk because of just blindly accept certificates. Such a tool did tag our code because we have such an implementation (which then is actually never be used). We should just change the impl to not do this as it does not matter for us and it makes such tools happier.

Modifications:

Throw CertificateException

51112e2b36 Avoid IdleStateHandler triggering unexpected idle events when flushing large entries to slow clients (#9020)
Motivation:

IdleStateHandler may trigger unexpected idle events when flushing large entries to slow clients.

Modification:

In netty design, we check the identity hash code and total pending write bytes of the current flush entry to determine whether there is a change in output. But if a large entry has been flushing slowly (for some reason, the network speed is slow, or the client processing speed is too slow to cause the TCP sliding window to be zero), the total pending write bytes size and identity hash code would remain unchanged.

Avoid this issue by adding checks for the current entry flush progress.

Result:

Fixes #8912 .

c3c05e8570 Fix NPE in OpenSslPrivateKeyMethodTest.destroy() when BoringSSL is not used
Motivation:

4079189f6b introduced OpenSslPrivateKeyMethodTest which will only be run when BoringSSL is used. As the assumeTrue(...) also guards the init of the static fields we need to ensure we only try to destroy these if BoringSSL is used as otherwise it will produce a NPE.

Modifications:

Check if BoringSSL is used before trying to destroy the resources.

Result:

No more NPE when BoringSSL is not used.

Allow to offload / customize key signing operations when using BoringSSL. (#8943)
Motivation:

BoringSSL allows to customize the way how key signing is done an even offload it from the IO thread. We should provide a way to plugin an own implementation when BoringSSL is used.

Modifications:

- Introduce OpenSslPrivateKeyMethod that can be used by the user to implement custom signing by using ReferenceCountedOpenSslContext.setPrivateKeyMethod(...)
- Introduce static methods to OpenSslKeyManagerFactory which allows to create a KeyManagerFactory which supports to do keyless operations by let the use handle everything in OpenSslPrivateKeyMethod.
- Add testcase which verifies that everything works as expected

Result:

A user is able to customize the way how keys are signed.

4373a1fba2 Increase default bits for SelfSignedCertificate (#9019)
Motivation:
During OpenSsl.java initialization, a SelfSignedCertificate is created
during the static initialization block to determine if OpenSsl
can be used.

The default key strength for SelfSignedCertificate was too low if FIPS
mode is used and BouncyCastle-FIPS is the only available provider
(necessary for compliance). A simple fix is to just augment the key
strength to the minimum required about by FIPS.

Modification:
Set default key bit length to 2048 but also allow it to be dynamically set via a system property for future proofing to more stricter security compliance.

Result:
Fixes #9018

We should fail fast if the given PrivateKey or X509Certificate chain is not supported by the used SslProvider. (#9009)
Motivation:

Some SslProvider do support different types of keys and chains. We should fail fast if we can not support the type.

Related to https://github.com/netty/netty-tcnative/issues/455.

Modifications:

- Try to parse key / chain first and if if this fails throw and SslException
- Add tests.

Always include initial handshake exception when throwing SslHandshakeException (#9008)
Motivation:

Remove call to SSL.setHostNameValidation(...) as it is done in the TrustManager (#8981)
Motivation:

We do not need to call SSL.setHostNameValidation(...) as it should be done as part of the TrustManager implementation. This is consistent with the JDK implementation of SSLEngine.

Modifications:

Remove call to SSL.setHostNameValidation(...)

Result:

More consistent behaviour between our SSLEngine implementation and the one that comes with the JDK.

Use SSL.setKeyMaterial(...) to test if the KeyManagerFactory is supported (#8985)
Motivation:

Modifications:

Use SSL.setKeyMaterial(...) as replacement for SSL.setCertificateBio(...)

Result:

Use the same method call to detect if KeyManagerFactory can be supported as we use in the real implementation.

Consolidate creation of SslHandshakeException when caused by a callback that is used in the native SSL implementation. (#8979)
Motivation:

We have multiple places where we store the exception that was produced by a callback in ReferenceCountedOpenSslEngine, and so have a lot of code-duplication.

Modifications:

- Consolidate code into a package-private method that is called from the callbacks if needed

Result:

Less code-duplication and cleaner code.

Support delegating task when using ReferenceCountedOpenSslEngine. (#8859)
Motivation:

SSLEngine API has a notion of tasks that may be expensive and offload these to another thread. We did not support this when using our native implementation but can now for various operations during the handshake.

Modifications:

- Support offloading tasks during the handshake when using our native SSLEngine implementation
- Correctly handle the case when NEED_TASK is returned and nothing was consumed / produced yet

Result:

Be able to offload long running tasks from the EventLoop when using SslHandler with our native SSLEngine.

While the exception is kind of harmless (as we will reject the renegotiation at the end anyway) it produces some noise in the logs.

Modifications:

Don't remove engine from map after handshake is complete but wait for it to be removed until the engine is destroyed.

Result:

No more NPE and less noise in the logs.

e609b5eeb7 Close consumed inputs in ChunkedWriteHandler (#8876)
Motivation:

ChunkedWriteHandler needs to close both successful and failed
ChunkInputs. It used to never close successful ones.

Modifications:

* ChunkedWriteHandler always closes ChunkInput before completing
the write promise. 
* Ensure only ChunkInput#close() is invoked
on a failed input.
* Ensure no methods are invoked on a closed input.

Result:

Fixes https://github.com/netty/netty/issues/8875.

Correctly resume wrap / unwrap when SslTask execution completes (#8899)
Motivation:

fa6a8cb09c introduced correct dispatching of delegated tasks for SSLEngine but did not correctly handle some cases for resuming wrap / unwrap after the task was executed. This could lead to stales, which showed up during tests when running with Java11 and BoringSSL.

Modifications:

- Correctly resume wrap / unwrap in all cases.
- Fix timeout value which was changed in previous commit by mistake.

Result:

No more stales after task execution.

Support using an Executor to offload blocking / long-running tasks wh… (#8847)
Motivation:

The SSLEngine does provide a way to signal to the caller that it may need to execute a blocking / long-running task which then can be offloaded to an Executor to ensure the I/O thread is not blocked. Currently how we handle this in SslHandler is not really optimal as while we offload to the Executor we still block the I/O Thread.

Modifications:

- Correctly support offloading the task to the Executor while suspending processing of SSL in the I/O Thread
- Add new methods to SslContext to specify the Executor when creating a SslHandler
- Remove @deprecated annotations from SslHandler constructor that takes an Executor
- Adjust tests to also run with the Executor to ensure all works as expected.

Result:

Be able to offload long running tasks to an Executor when using SslHandler. Partly fixes https://github.com/netty/netty/issues/7862 and https://github.com/netty/netty/issues/7020.
